We're dividing 237403 by 25 
The aim is to understand the frequency of 25 in 237403.

Going ahead to step 1:
The number 25 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 25

Let's proceed to step 2:
25 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 25

Step 3:
237 divided by 25 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 225 from 237, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 25

Advancing to step 4:
124 divided by 25 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we take 100 away from 124, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 25

Step 5:
If we divide 240 by 25, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 949.0
Subtract 225 from 240 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 25

Moving on to step 6:
153 divided by 25 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 9496.0
If we subtract 150 from 153, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 9496.1
If we subtract 25 from 30, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 9496.12
If we take 50 away from 50, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9496.12
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9496.12
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9496.12, with a leftover of 0.0.
